Hydraulic Impact Hammers (HIH)

APE hydraulic impact hammers are made for short head room operations. They incorporate a patent pending hydraulic cylinder that lifts the ram
from the bottom, thus eliminating the need for a tall hammer. Rams are one peice. There are no sensors to break due to a new check valve system
developed by APE.

APE designed and built the first real low headroom hydraulic impact hammer in response to California’s 1989 earthquake. The proceeding seismic retrofit
repairs meant that thousands of piles, some over 100 feet long, had to be driven underneath existing bridges demanding equipment that could drive the piles
and minimize splicing. The job called for very short hammers. APE designed an impact hammer that features a Patented, US-006557649, hydraulic cylinder
that connects through the center of the ram above the impact point. This technique greatly reduces the overall height of any comparable hammer by more than
half. APE’s low headroom technology has revolutionized pile driving, as contractors have discovered they can drive longer piles without splicing and welding.
Since then, the APE hydraulic impact hammer has evolved into a full line of tools including the largest hydraulic impact hammer made in North America.
